Vertically stacking two-dimensional (2D) materials to form van der Waals homo- or hetero-structures has become an effective means for regulating their physical and mechanical properties. In particular, when a small twist angle is present at the stacked interface, the 2D structures often show many interesting and even magical physical phenomena owing to the unique interlayer coupling.
